Abstract

In the changing device, the base jaw (1) and the exchangeable jaw (2) are connected to one another in a positive-locking manner by means of a clamping screw (3) via a pointed tooth system (4) and are provided with slots (5, 6) facing one another, of which the slot on the base jaw is designed as a T-slot (5) for accommodating tenon blocks (7) which are supported in the T-slot (5) in the direction towards the exchangeable jaw (2) and engage in the groove (6) of the exchangeable jaw (2) for tangentially positioning the same. The exchangeable jaw (2) carries an anchor (11) which projects into the T-slot (5) and has an anchor head (13) widening in the radial direction on either side with one wedge surface (12) each. One tenon block (7) each bears against the wedge surfaces (12) of the anchor head (13). The clamping screw (3) passes radially through the anchor head (13) in a bore (16) and restrains the tenon blocks (7) against one another via the anchor head (13). <IMAGE>
